Custom power supplies from BEAR are compact and reliable

BEAR excels at custom power supply design and manufacturing. From mW to KW, we create AC/DC, DC/AC or DC/DC converters in open frame, enclosed or encapsulated packages to suit your needs.

Our custom power converters are compact and rugged. Like all BEAR power supplies, they are designed and built for long life and reliable operation over a wide operating temperature range.

BEAR custom power supplies are used in a wide range of industrial, commercial and medical applications - from military and telecom to LED lighting and portable systems. We specialize in meeting unusual requirements. Try us!

Why work with BEAR?

First: Expertise. We understand how to make rugged, reliable power supplies.

Second: We’re easy to work with. Our engineering and manufacturing teams work together in one location, conveniently located in western New York. We focus on understanding your real needs, offering expert guidance on your specs, and creating highly manufacturable products.

You’ll go from concept to prototype to production -- quickly and cost effectively -- without the communication issues and delays you can experience with offshore manufacturers.

Our NRE charges are reasonable, and we'll take on custom power supply jobs with lower production volumes than many other suppliers. We currently produce custom power supplies in quantities from 50 to 50 thousand per year.

BEAR custom power supply gallery
	660 Watt AC/DC power supply ultra-low leakage current for medical instruments very low leakage current (5 µA) exceeds standards for Type CF medical equipment 3 isolated outputs universal input with PFC front end This custom medical power supply includes a unique "self-monitoring" feature with built-in digital reporting of output voltages, current and operating temperatures.
	10 Watt constant power DC/DC converter for a portable lighting application high efficiency high power density constant output power as input battery voltage changes Innovative custom design allows our customer to use one standard power supply unit across their entire product line, replacing four different power supplies and extending the input voltage range at the same time.
	"Working with BEAR’s USA-based design and manufacturing team is a plus. They anticipated our needs, made excellent design recommendations, and provided fast turn-around." - Bob Cook, president Velocite Systems
	180 Watt custom DC/DC converter for ground transportation instrument 4,000 VAC input/output isolation very long life low input and output noise Designed to meet a requirement for extremely high input/output isolation, this custom DC/DC converter also allowed our customer to reduce the size and cost of their existing system.
	850 Watt custom DC/DC converter for mobile communications system 3 isolated outputs hot-swappable with load sharing stringent mechanical constraints Rugged custom design with specific mechanical constraints is used in a rack-mounted system in a mobile communications unit.
"BEAR employees are great to work with and very responsive to my needs." - Bob Lindley, Hardware Design Engineer Sensis Corporation
	Rack-mounted AC/DC converter for industrial monitoring instrument PFC input / 60W output Minimum 10-year life required 24/7 operation in a fanless system Custom mechanical design This customer required very high reliability and long life. They also had specific mechanical configuration and input connector requirements.
	300 Watt DC/DC converter for commercial telecom system Four different outputs Input - 48VDC High efficiency High efficiency allows this unit to be cooled with a single fan. It replaced an off-shore manufacturer’s power supply that is less efficient and required two large cooling fans. BEAR's mechanical design recommendations allowed our customer to remove other hardware costs from their system.
	"From the initial call, the customer was very impressed with BEAR’s knowledge and support for custom power supply design." – Perry Thornton, sales representative Pinnacle Marketing
	60 Watt AC/DC converter for a portable medical instrument High efficiency over very wide input voltage and load range Mechanically rugged Entire heat load contained in a sealed unit Special input connector allows system to be washed down and disinfected without leaking or degrading For this custom medical power supply, BEAR passed stringent testing requirements that the customer's offshore supplier had been unable to meet.
	1.5 Watt mini DC/DC converter for portable military communications system 100VDC output Wide operating temperature range: -55 to +85°C High efficiency Small size 0.5 x 0.5 x 0.4 inches (12.7 x 12.7 x 10.2 mm) BEAR now offers this custom supply as a standard configurable product. See our DC/DC power supplies.
"We're pleased to be working with [BEAR parent company] Z-AXIS, which was highly recommended by other groups within Harris for its quality and on-time delivery." - Thomas Kenny, vice president of product line management Harris RF Communications
	(prototype) 620 Watt custom AC/DC supply with PFC for commercial telecom Designed for long life in a fanless system Very low input noise 3 outputs Hot-swappable with load sharing on each output Photo shows working prototype.
